720 ILCS 5/38-2
The State's Attorney is authorized to institute civil proceedings in the Circuit Court to enjoin the operation of any business other than a corporation, including a partnership, joint venture or sole proprietorship. The Court may grant the injunction upon finding that (a) any person in control of any such business, who may be a partner in a partnership, a participant in a joint venture, the owner of a sole proprietorship, an employee or agent of any such business, or a person who, in fact, exercises control over the operations of any such business, has, in conducting its business affairs, purposely engaged in a persistent course of intimidation, coercion, bribery or other such illegal conduct with the intent to compel other persons, firms, or corporations to deal with such business, and (b) that for the prevention of future illegal conduct of the same character, the public interest requires the operation of the business to be enjoined.
